Actually, there are many solid reasons for Slavs not being NS. How much anti-Slavism is there in NS is debatable, however Germans were responsible for deaths of many Slavs and you can't ignore that. Of course you can say that Germany was right and that Slavs were enemies of NS, however you will hardly find anyone whose grandfather was killed by Germans in WWII to support National-Socialism.

Also, I think people here should more identify with their own national symbols rather than swastikas or other "Aryan" symbols.
